IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent N0. 130,269, dated August6, 1872.

To aZlpe-rsons to whom these presents may come:

Be it known that I, J oHN ANDREWS, of Marlborough, of the county ofMiddlesex and State of Massachusetts, have invented a new and usefulSash Bolt and Fastener; and do hereby declare the same to be fullydescribed in the following Specification and represented in theaccompanying drawing, of which Figure 1 is a view of it as applied tothe left vertical bar of a window-sash. Fig. 2 is a rear side view ofit, and Fig. 3 is a longitudinal section of it as separated from thesash-bar. Figs. 4 and 5 are edge views of it. Figs. 6 and 7 are endviews of it.

This fastener is intended to secure the sash at any desirable elevationwithin the range of its motion or at either extreme thereof, it beingunderstood that there are to be in the Window-frame of such sash one ora series of boltholes for reception of the bolt, in order for it to lockthe sash to theframe.

The bolt Ais cylindrical, and constructed with a handle, a, and. ashank, b, arranged as shown, the space about the shank being to receivea helical spring, B, one end of which is to rest against a shoulder, c,and the other of which against therear end of the bolt-case, all beingas shown. The said bolt-case is exhibited at O as formed tubular toreceive the bolt-guide in its longitudinal movements, and admit of itbeing revolved transversely to its axis, either in one direction or theopposite, one hundred and eighty degrees of a circle or thereabout.Furthermore, the said case is provided with ears d d extended from ormaking part of it, as represented, and being to enable it to be securedto the sash-bar D by screws 0 6 going through such ears and beingscrewed into the bar, the latter being duly socketed to receive thecase. Such case also has a trapezoidal opening, E, made through or init, in manner as shown, there being extended into such opening a stud,g, projected from the bolt. The bases of the said trapezoidal openingserve as stops to arrest, by means of the stud g, the bolt at thetermini of its rotary movements. When the stud g is against the lesserbase such stud will also rest against the longest side h of thetrapezoidal opening, and thus the said side and the stud Will serve toretain the bolt in its rearmost positionviz., wholly back in the case.

By turning the bolt so as to cause the stud to pass from the longer tothe shorter base of the trapezoidal opening the stud will be movedagainst the oblique side or cam h of the opening, and as a consequencewill be forced back in the case, the spring within the case and aroundthe bolt operating to advance the bolt .When it may next be turned inthe reverse direction. The trapezoidal opening admits of the bolt, whenthe stud is against the longer base or in any position between the twobases of such opening, being retracted by a persons hand applied to thehandle of the bolt. Near the lesser base of the trapezoidal opening theoblique side of such opening is formed square to the base for a distanceequal to or somewhat greater than the radius of the cross-section of thestud or such oblique side may be notched a little, such being to insurethe bolt from bein g shot forward by the spring when the stud may beagainst the lesser base of the opening.

The above-described sash-fastening is to be mortised into the side ofthe sash and work in openings in the window-frame.

I claim The bolt furnished With the stud g, which works in thetrapezoidal opening E, and with the operating-knob a, arranged in linewith the bolt itself, and the coiled spring B, said bolt, when inmovement, having a longitudinal as well as a rotary motion, all as setforth.

JOHN ANDREWS.
